By default, the server sends the requested file to the client by calling
the send-file function. The directive that
sets the default is:

Service method="(GET|HEAD)" type="*~magnus-internal/*" fn="send-file"

This directive usually comes last in the set of Service-class
directives to give all other Service directives a chance
to be invoked. This directive is invoked if the method of the request is GET, HEAD, or POST, and the
type does not start with magnus-internal/.
Note here that the pattern *~ means “does not match.”
For a list of characters that can be used in patterns, see the Sun Java System Web Server 6.1 SP10 NSAPI Programmer’s Guide.

The following Service-class functions are described
in detail in this section:

add-footer appends a footer
specified by a file name or URL to an HTML file.

add-header prepends a header
specified by a file name or URL to an HTML file.

match-browser matches specific
strings in the User-Agent string supplied by the browser,
and then modifies the behavior of Sun Java System Web Server based upon the
results by setting values for specified variables.
